Scored 15 goals in 2 seasons. Gave a secret interview criticizing the manager. Got loaned back to Inter. Then loaned to Roma. Chelsea still paying part of his wages. The worst big-money signing in PL history.
The most expensive goalkeeper ever. Refused to be substituted in a cup final. Made errors that cost points weekly. Benched by a cheaper replacement. The £71.6M mistake that taught Chelsea about market inflation.
Liverpool used the money to buy Van Dijk and Alisson and won the Champions League. Coutinho scored a hat-trick against Barça while on loan at Bayern. The transfer that helped Liverpool and destroyed Barcelona.
3 goals in 32 PL appearances. The piano video. The memes. United were reportedly paying him £75,000 per touch at one point. The worst free transfer in football history — because it wasn't really free.
Not a disaster, but £100M for 20 goals in 3 seasons? City won everything anyway. Grealish is a good player — but £100M good? The market said yes. The stats say maybe not.
